\ExpandSecondAfter is MkII only, so I cannot use it for code that is to
be used in both MkII and MkIV. So, I re-request my original proposal:

in core-gen.mkii

\def\p!doifinsetelse#1#2#3#4%
{\donefalse
\edef\!!stringa{#3}%
\ifx\!!stringa\empty
\else
- \processcommalist[#4]\p!docheckiteminset
+ \processcommacommand[#4]\p!docheckiteminset
\fi
\ifdone\expandafter#1\else\expandafter#2\fi}


I cannot oversee the consequences of that.

Can't you wrap your call in

\expanded{\doifinsetelse{...}{...}} {} {}

this should work in both mk's

No. Not without a lot of \noexpand. I'll add a macro that expands to 
\ExpandSecond after in MkII and \relax in MkIV.
